                  difficult conventional procedures (NDB and
                  Circling)
                • Stabilised approaches
       •      Flexibility - revised sectors
       •      Environment
       •      Cost savings through shorter routes
       •      Effective use of existing equipment

       Issues               - Airspace Design and Route Spacing
       • Revise Sectorisation
       • Introduce co-operative planning
       • Route spacing criteria needed for P-RNAV
         and RNP x RNAV.
       • Resolve conflict between Annex 11 definition
         of RNP4 procedural spacing criteria and
         EUROCONTROL B-RNAV safety case.
       • Provide clear definition of ‘protected area’
       • Address separation from military airspace.

     Issues                 - Quality Assurance and Data Integrity
       • Harmonised method for applying CRCs.
       • Standards for procedure designers.
       • Widen ICAO Safety Oversight Programme to include
         PANSOPS issues.
       • Encourage implementation of QA procedures and
              application of ED 77/DO 201A.
       • Encourage implementation of existing ICAO
         standards (Annex 4, 15 and PANS-OPS)
       • Need for adherence to AIRAC dates
       • Many aircraft have limited database capacity
       • ARINC 424 format showing age but unlikely to be
         replaced in near future.

                            Issues - Publication
         • No standardisation of commercial charts
         • Standards for AIS staff
         • Standardisation of naming convention
         • Lack of co-ordination between designer and
           database coder
         • Standards for RNAV charts
                 • True bearings?
                 • Co-ordinates - only runway threshold?
         • Define RNAV Transitions in ICAO material

                    Issues - Implementation of RNAV
                               Procedures
       •      New design criteria.
       •      Need to understand coding issues.
       •      Need for validation - what tools?
